Sailor Speak of the Week – Yardarm



  • The outer portions/tips of a yard (the athwartship spars that hold square sails).
  • The athwartship spar on naval, merchant, and recreational vessels for mounting signals.


15th century.


This term only applies to the outer sections of a yard, not the entire yard itself. During the age of sail, signal flags would be flown from yardarms. Sailors who were court-martialed and sentenced to death by hanging would also be hung from a yardarm.
